This article relates to a granular pesticide mixture kit. The present invention also provides a method for evaluating the uniformity of individual granular pesticide compositions in the mixed granular pesticide composition and granular pesticide mixture, and a granular pesticide composition suitable for the mixed granular pesticide composition, as well as its use. Also related.

Conventionally, various formulations of agricultural chemical formulations are known, such as powders, wettable powders, aqueous suspensions, and emulsions, one of which is granules. Granules are a safe dosage form with little concern about exposure to pesticide application workers due to the powdering of the pesticide active ingredient and negative effects on the surrounding environment due to scattering during spraying, and the application rate per unit area is 10 are. It has a relatively small amount of 0.2-5 kg, and has been supported by the spread of power sprayers that can be used for granule treatment in recent years, and has become popular among consumers in Japan due to the ease of applying pesticides. Widely accepted. In addition, there is a high degree of freedom in formulation design, and it is easy to control the elution characteristics of pesticide active ingredients and other physicochemical properties of pesticide formulations, making it easy for both suppliers and consumers to achieve the desired performance. It is.

By the way, harmful organisms that are targets of agricultural control include plants (weeds), animals (pests), and microorganisms (phytopathogenic fungi and bacteria, etc.), but there are many types of pests that can be controlled and are effective against all of them. There is no universal pesticide active ingredient that does not have a negative effect on plants, and in modern agriculture, herbicidal active ingredients are used to control weeds, insecticidal active ingredients are used to control pests, and fungicidal active ingredients are used to control diseases. Agricultural land, etc. is managed in accordance with the above. Furthermore, it is not always the case that a single herbicidal active ingredient, a single insecticidal active ingredient, or a single fungicidal active ingredient is effective in controlling all weeds, all insect pests, or all microorganisms; Usually, there are grass species, insect species, or fungal species that are highly susceptible and grass species, insect species, or fungal species that are less susceptible. Under these circumstances, in order to control all the pests in a wide variety of agricultural lands, etc., it is often necessary to use a combination of a plurality of agrochemical active ingredients depending on the target to be controlled.

To meet these needs, there are several mixtures on the market that are pre-blended with multiple pesticide active ingredients, but the number of combinations of pesticide active ingredients that are required is enormous, and all of them are commercially available as mixtures. It is virtually impossible to do so. In addition, each pesticide active ingredient has unique physicochemical properties, and for example, acidic pesticide active ingredients and basic pesticide active ingredients may have a negative effect on the stability of each other. There are also combinations that are difficult to form into agents. Furthermore, in the case of granules, the surface of the granular composition may be coated with hydrophobic fine powder, resin, etc. in order to control the elution characteristics into a preferable pattern depending on the characteristics of the agriculturally active ingredient contained in the granules. In some cases, the granular composition may be provided with elution control means such as forming a matrix of thermoplastic material, but such elution control means prevent the elution of all pesticide active ingredients contained in the granule. Since this affects the properties, it may not be possible to use a mixture containing a plurality of agrochemical active ingredients with different preferred elution patterns.

Therefore, when applying a combination of agrochemical active ingredients for which a mixture is not commercially available to agricultural land, etc., it is necessary to separately prepare agrochemical compositions containing each agrochemical active ingredient and perform the agrochemical application. However, it requires a lot of labor and effort for farmers to perform complicated pesticide application work for each number of pesticide compositions prepared above, so it is necessary to mix multiple pesticide compositions on-site and apply the mixture. Spraying is widely used to complete the application of pesticides in one operation. When performing the above operations on granules or granular compositions, a plurality of granules are mixed and treated simultaneously. In addition, in order to formulate a plurality of agricultural chemical active ingredients that are difficult to formulate into a granule and package the product in a single package, granular agricultural chemical compositions containing individual agricultural chemical active ingredients are prepared separately. However, granular pesticide mixtures made by mixing them in a predetermined ratio are also known.

However, in order to uniformly and simultaneously apply a plurality of granular compositions having different compositions, it is necessary that the granular compositions be mixed sufficiently uniformly. Since granular materials have large particle sizes and cannot be micromixed like powdered materials, they tend to be unbalanced due to classification and the like. When applying a mixture of granular agricultural chemical compositions that are not sufficiently uniformly mixed, the application will be uneven, and even if the expected amount is applied to the entire application area, only a portion of the application area will be sprayed. In some cases, a lack of agrochemical active ingredients may result in a lack of medicinal efficacy, and at the same time, an excess of another agrochemical active ingredient may cause drug damage. In addition, in the production of granular pesticide mixtures, unless the granular pesticide compositions containing individual pesticide active ingredients are packaged in a sufficiently uniformly mixed state, it is necessary to package the granular pesticide compositions containing all the pesticide active ingredients in the desired amount at the same time. It cannot be used as a pesticide mixture. Therefore, many studies have been conducted to achieve sufficient uniform mixing of the granular agricultural chemical compositions, and various techniques have been proposed so far (Patent Documents 1 to 6).

Japanese Patent Application Publication No. 2000-86405 Japanese Patent Application Publication No. 2001-17847 Japanese Patent Application Publication No. 2001-206802 Japanese Patent Application Publication No. 2004-352711 Japanese Patent Application Publication No. 2007-176920 Special Publication No. 2011-502138

However, whether the granular pesticide compositions are actually mixed sufficiently uniformly can be determined by sampling the mixed granular pesticide composition and quantifying the individual pesticide active ingredients using an analytical device such as a liquid chromatograph. There is no way to check whether the mixed granular pesticide composition The reality is that the only way to apply pesticides is to trust that they are sufficiently uniform. In addition, in the production of granular agricultural chemical mixtures, the content of agricultural chemical active ingredients in the granular agricultural chemical mixtures immediately before packaging is confirmed by instrumental analysis, but it is important to check whether the granular agricultural chemical mixtures that are being mixed are already homogeneous. In other words, it is not possible to tell whether or not it is okay to end the mixing process by looking at the composition being mixed, and in the end, based on experience, the mixing process must be carried out for a long enough time before the production line is placed on standby. Given the current situation, there was no other choice but to conduct an instrumental analysis to determine the completion of mixing. Furthermore, granular agricultural chemical compositions have a phenomenon in which the particles gradually disintegrate during the mixing process, so if they are mixed for a long time, non-standard fragments and powder due to friction will increase, leading to losses in the manufacturing process. Therefore, it is desirable to stop the mixing process as soon as the mixture is uniformly mixed, and a simple judgment method for monitoring the mixing state has been desired.

Therefore, the present invention provides a mixed granular agrochemical composition that allows the uniformity of a mixed granular agrochemical composition to be easily determined without the need for troublesome instrumental analysis, and that allows those engaged in pesticide application work to use the agrochemical composition with a sense of security. The object of the present invention is to provide a granular agrochemical composition for obtaining an agrochemical composition and the like.

As a result of intensive research aimed at solving the above problems, the present inventors have found that two or more types of granular agricultural chemical compositions constituting a mixed granular agricultural chemical composition have a color difference of a certain level or more. When granular agricultural chemical compositions are mixed to form a mixed granular agricultural chemical composition, and when two or more types of granular agricultural chemical compositions are mixed in the field to form a mixed granular agricultural chemical composition, that is, at least at the time of use, the granular agricultural chemical composition The present inventors have discovered that the uniformity of a mixed granular agricultural chemical composition, which is a mixture of substances, can be visually confirmed, leading to the completion of the present invention.

Since the mixed granular agricultural chemical composition of the present invention allows visual confirmation of its uniformity, there is no need for troublesome instrumental analysis. Therefore, the mixed granular agricultural chemical composition of the present invention can be easily evaluated for uniformity and controlled for quality.

In addition, since the mixed granular agricultural chemical composition of the present invention can be uniformly sprayed when applied, it goes without saying that the desired medicinal efficacy can be achieved, and the granular agricultural chemicals constituting the mixed granular agricultural chemical composition can be sprayed uniformly. Since the mixing state of the compositions is obvious at a glance, it is possible to prevent accidents in which the classified mixed granular agricultural chemical composition is applied unevenly. Furthermore, by providing visual information about the uniformity of the mixed granular agricultural chemical composition to agricultural workers, it is possible to provide the mixed granular agricultural chemical composition that can be used with a sense of security. In addition, in the mixing process, unnecessary long-time mixing aimed at uniform mixing can be eliminated, and damage to grains in the mixing process can be minimized.

The mixed granular agricultural chemical composition of the present invention is a mixture of two or more types of granular agricultural chemical compositions having different compositions, at least at the time of use. This includes cases where two or more types of granular agricultural chemical compositions are mixed in advance to form a mixed granular agricultural chemical composition, and cases where two or more types of granular agricultural chemical compositions are mixed in the field to form a mixed granular agricultural chemical composition. .

The color difference ΔE ^* expressed in the CIE1976 color space (L ^* a ^* b ^* color system) of any two types of granular pesticide compositions contained in the mixed granular pesticide composition is 4.5 or more, preferably 5. It is 0 or more. This color difference ΔE ^* is determined by measuring the color coordinates of each granular agricultural chemical composition in the CIE1976 color space using a commercially available colorimeter, and using the formula described in the examples below for any two types of granular agricultural chemical compositions. Alternatively, the color difference ΔE ^* between any two types of granular agricultural chemical compositions may be directly determined using a commercially available color difference meter. The common technical knowledge that correlates the value of color difference ΔE ^* with human sensation is "Science of Food Color" (edited by Susumu Saito, Koshobo, 1997), p. There is a table described in 185, but the correspondence table correlates well with the degree of perception when two objects of a certain size, such as food, are compared adjacently or separated, but when one grain is several mm or When observing a mixed agricultural chemical granular composition in which a large number of each of the fine agricultural chemical granular compositions are mixed together, this is not valid. For example, when the color difference ΔE ^* between two objects is between 0.8 and 1.6, the above correspondence table discloses that the color difference is at a level where "a slight color difference can be perceived by adjacent comparison." In a mixed agricultural chemical granular composition consisting of two types of agricultural chemical granular compositions having a large color difference, it is almost impossible for an ordinary person to perceive the color difference between the two. If the mixture is in a fluid state, such as during mixing, this perception becomes even more difficult. In order for humans to perceive the color difference of the mixed pesticide granular composition, a color difference ΔE ^* of at least 4.5 is required, despite the above-mentioned common general knowledge. When there is such a color difference ΔE ^* , it becomes possible to visually recognize whether the two are uniformly mixed in the mixed granular agricultural chemical composition or whether they are classified. Here, the upper limit of the color difference ΔE ^* is not particularly limited, and even if it is, for example, 25 or less, or 13 or less, or even 6.5 or less, the above visual recognition is sufficiently possible. Of course, there is no problem if the color difference ΔE ^* exceeds 25. Note that the CIE 1976 color space (L ^* a ^* b ^* color system) was formulated by the International Commission on Illumination.

Each of the granular agricultural chemical compositions constituting the mixed granular agricultural chemical composition of the present invention contains one or more agricultural chemical active ingredients. The agrochemical active ingredient is not particularly limited, and for example, the following known herbicidal active ingredients, fungicidal active ingredients, insecticidal active ingredients, and plant growth regulating active ingredients can be used.

Since the individual granular agricultural chemical compositions constituting the mixed granular agricultural chemical composition of the present invention are planned to be finally mixed to form a uniform mixed granular agricultural chemical composition, they have shapes and sizes that are difficult to classify. Needless to say, it is preferable to have a certain size and mass. Here, in any two types of granular agricultural chemical compositions constituting the mixed granular agricultural chemical composition, both shapes may be the same or different, but when they have the same shape, it is difficult to classify each other. The same shape is preferably cylindrical, approximately cylindrical, spherical, or approximately spherical. In addition, the minor axis of one of the two arbitrary types of granular agricultural chemical compositions is 60-167% of the other, preferably 70-143%, more preferably 80-125%, still more preferably 90-112%, most ideally When they are 100%, it becomes difficult to classify each other, and the average mass per grain of one is 60-167% of the other, preferably 70-143%, more preferably 80-125%, even more preferably 90- Even when it is 112%, most ideally 100%, it is difficult to classify each other.

Furthermore, the short axis of the mixed granular agricultural chemical composition of the present invention and the individual granular agricultural chemical compositions constituting it is usually about 0.3 to 10 mm, but is not particularly limited. The major axis is also not limited, but is usually about 1-5 times, preferably about 1-4 times, and more preferably about 1-3 times the minor axis. One type of granular agricultural chemical composition is a large granular agricultural chemical composition suitable for water surface application, which has a short axis of 3 mm or more, has the property of floating on the water surface, and the property of disintegrating within 30 minutes after being dropped into water. As is known, the large granular agricultural chemical composition has a large volume per particle, so it is difficult to move within the entire mixed granular agricultural chemical composition, and therefore it is difficult to move the mixed granular agricultural chemical composition composed of the large granular agricultural chemical composition. In order to achieve uniformity, more careful mixing is required than when obtaining a mixed granular agricultural chemical composition composed of smaller granular agricultural chemical compositions, and it is extremely difficult to judge the end point of such mixing. In addition, large granular agricultural chemical compositions that have both the property of floating on the water surface and the property of disintegrating within 30 minutes after being dropped into the water are susceptible to damage to the particles during the mixing process, so it is necessary to avoid mixing more than necessary. There is. The present invention is also suitable for mixed granular agricultural chemical compositions comprising such large granular agricultural chemical compositions.

The individual granular agrochemical compositions constituting the mixed granular agrochemical composition of the present invention described above can be manufactured by conventional methods. Namely, stirring and mixing granulation method, rolling granulation method, extrusion granulation method, crushing granulation method, fluidized bed granulation method, composite granulation method, spray drying granulation method, melt granulation method, compression granulation method. method, vacuum freezing granulation method, suspension agglomeration granulation method, coating granulation method, etc. are applicable, and are not limited in any way, but among the above granulation methods, extrusion granulation method in particular It is a granulation method that allows the agrochemical composition to be easily formed into the above-mentioned shape and whose minor axis can be easily adjusted within the above-mentioned predetermined range. It is particularly suitable as a manufacturing method.

Preferred forms of the mixed granular pesticide composition of the present invention include a granular pesticide mixture kit in which the granular pesticide compositions constituting the mixed granular pesticide composition are each packaged in separate packages, and a granular pesticide mixture kit in which the granular pesticide compositions are packaged in advance. Examples include granular pesticide mixtures that are mixed and packaged in a single package.

When the mixed granular agrochemical composition of the present invention is a granular agrochemical mixture kit, a person engaged in agricultural work at a pesticide application site such as an agricultural land, immediately before applying the agrochemical, can prepare the individual granular agrochemical compositions before use. can be obtained by mixing. When the mixing is sufficiently performed, the individual granular pesticide compositions constituting the mixed granular pesticide composition are randomly arranged in the whole mixed granular pesticide composition, but in the mixed granular pesticide composition of the present invention, Since the color tones of the individual granular agricultural chemical compositions that constitute the composition differ to such an extent that a person can distinguish them at a glance, the mixed granular agricultural chemical composition as a whole exhibits a mosaic-like appearance. As a result, those engaged in agricultural work can be confident that the mixed granular pesticide composition has been mixed uniformly, so they can finish mixing without worrying that the mixture is insufficient. Application operations of mixed granular pesticide compositions can be carried out. If desired, the mixed granular agricultural chemical composition exhibiting a mosaic-like appearance can be photographed in advance, and the photograph can be used as a work record to ensure that the mixed granular agricultural chemical composition has been homogenized.

If you want to be more confident, for example, randomly sample a predetermined amount of the mixed granular pesticide composition, sort out the individual granular pesticide compositions based on differences in color tone, and then use a scale to sort out each granular pesticide composition. A method of measuring the mass of the composition and comparing the mass ratio of each granular pesticide composition actually measured with the mass ratio of each granular pesticide composition in the entire mixed granular pesticide composition, and By a method of measuring the number of grains of the granular agricultural chemical composition and comparing the grain number ratio of each of the actually measured granular agricultural chemical compositions with the mixed grain number ratio of each granular agricultural chemical composition in the entire mixed granular agricultural chemical composition, etc. You can easily quantitatively check the mixing state of each granular pesticide composition in a mixed granular pesticide composition at the pesticide application site without using large-scale and expensive equipment that can analyze pesticide active ingredients, and if you wish, you can write it down. Using these numerical values, it is also possible to record the work in which the mixed granular agricultural chemical composition was reliably homogenized.

Moreover, when the mixed granular agricultural chemical composition of the present invention is a granular agricultural chemical mixture, it can be obtained by mixing individual granular agricultural chemical compositions by the agricultural chemical manufacturer at a manufacturing site such as an agricultural chemical factory. In this case, the obtained mixed granular agricultural chemical composition is packaged in a single package as a granular agricultural chemical mixture, but as already mentioned, it is difficult to judge the end of the mixing step during the manufacturing process of the granular agricultural chemical mixture. As expected, those who manufacture granular pesticide mixtures made from the mixed granular pesticide composition of the present invention should perform process control by applying various methods for checking the mixing state of the mixed granular pesticide composition at the pesticide application site. It is easy to carry out, and it is also possible to control the quality of granular agricultural chemical mixtures using the same method.

Even after the mixed granular agricultural chemical composition of the present invention is applied to agricultural land, non-agricultural land, or seedling boxes that are not flooded, such application is uniformly carried out for each individual granular agricultural chemical composition in the mixed granular agricultural chemical composition. You can confirm that That is, as long as the agricultural land etc. is not flooded, the mixed granular agricultural chemical composition is exposed on the surface of the soil etc., so those who engage in agricultural work applying the mixed granular agricultural chemical composition of the present invention should not worry about the color tone. The number of particles of each granular agrochemical composition observed within a predetermined area is measured based on the difference, and the particle number ratio of each granular agrochemical composition actually measured and each granular agrochemical composition in the entire mixed granular agrochemical composition are calculated. By comparing the ratio of the number of mixed particles, it is possible to visually confirm that the individual granular agricultural chemical compositions in the mixed granular agricultural chemical composition have been uniformly sprayed.

Further, the mixed granular agricultural chemical composition of the present invention is applicable to all situations in agricultural chemical application. Specifically, these include mixing with the soil in paddy rice seedling boxes, sprinkling on the surface of the soil, hole treatment during transplanting, cropping row treatment, side row treatment, soil treatment, stem and leaf treatment, plant base treatment, and water surface treatment. Examples include application treatment and other treatments for cell trays, but are not particularly limited. The means of application is not particularly limited, and the same means as for general granules can be used, such as direct granulation by hand, manual granulation machine, electric granulation machine, backpack type power type. Spraying methods include granulators, traveling power granulators, tractor-mounted granulators, rice transplanter-mounted granulators, side-row application machines, and aerial granulators such as unmanned helicopters and drones. can.

[Test Example 1]
Put 50 grains of the granular agricultural chemical composition of Production Example 1 into a 50 mL screw tube, then put 50 grains of the granular agricultural chemical composition of Reference Production Example 1 into the same screw tube, and invert the screw tube 30 times at a speed of 30 rpm. The mixture was homogenized to prepare a mixed granular agricultural chemical composition. Furthermore, in place of the granular agrochemical composition of Production Example 1, the granular agrochemical composition of Production Example 2-5 was operated in the same manner to prepare a mixed granular agrochemical composition. This mixed granular agricultural chemical composition was observed, and the difficulty of visually recognizing that each particle was mixed uniformly was evaluated.
Table 1 shows a correspondence table between the color difference ΔE ^* of each granular agricultural chemical composition with respect to the granular agricultural chemical composition of Reference Production Example 1 and the observation evaluation results. Note that ΔE ^* was determined by the following formula.

[Test Example 2]
Put 50 grains of the granular agricultural chemical composition of Production Example 1 into a 50 mL screw tube, then put 50 grains of the granular agricultural chemical composition of Reference Production Example 1 into the same screw tube, invert the screw tube once at a speed of 30 rpm, A mixed granular pesticide composition was prepared. Furthermore, in place of the granular agrochemical composition of Production Example 1, the granular agrochemical composition of Production Example 2-5 was operated in the same manner to prepare a mixed granular agrochemical composition. In both cases, it is strongly assumed that the mixture is not sufficiently mixed, so the state is non-uniform. This mixed granular agricultural chemical composition was observed to see if it was possible to visually determine that the individual particles were not uniformly mixed.
Table 2 shows a correspondence table between the color difference ΔE ^* of each granular agricultural chemical composition with respect to the granular agricultural chemical composition of Reference Production Example 1 and the above investigation results.

[Test Example 3]
50 grains of the granular agricultural chemical composition of Production Example 1 and 50 grains of the granular agricultural chemical composition of Reference Production Example 2 were placed in the same glass cylinder with an inner diameter of 5 cm and a height of 14 cm, and both ends were sealed with mesh and homogenized by vigorous shaking. , a mixed granular pesticide composition was prepared. Furthermore, in place of the granular agrochemical composition of Production Example 1, the granular agrochemical composition of Production Example 2-5 was operated in the same manner to prepare a mixed granular agrochemical composition. The granular agrochemical composition of each production example and the granular agrochemical composition of Reference Production Example 2, which constitute each mixed granular agrochemical composition, have the same external shape except for the difference in color tone, but have significantly different specific gravity. . The cylinder containing the mixed granular agrochemical composition was stood upright, and compressed air was blown from the bottom side of the cylinder toward the upper side for 30 seconds to cause the mixed granular agrochemical composition to flow. Thereafter, the state of the mixed granular agricultural chemical composition was visually observed. Furthermore, 10 grains of the granular agricultural chemical composition were taken at random from the upper layer of the cylinder, and poured into water, and the number of grains that settled was counted. When the mixed granular agricultural chemical composition is uniform, the theoretical number of sedimented grains is 5 grains, and if classification is caused by the above-mentioned flow-based classification operation, the granular agricultural chemical composition of each production example will be in the upper layer of the cylinder, Since the granular agricultural chemical composition of Example 2 is concentrated in the lower layer, the actual number of sedimented particles decreases. The results are shown in Table 3.

In all the experiments shown in Table 3, the number of particles that settled in the water was 0 or 1, and almost all of the 10 particles collected from the upper layer of the cylinder were the granular agricultural chemical composition of each production example. From this, in this test, the granular agricultural chemical composition of each production example and the granular agricultural chemical composition of Reference Production Example 2 were classified due to the difference in specific gravity. Even in the case of the mixture of the granular agricultural chemical composition of Production Example 1 and the granular agricultural chemical composition of Reference Production Example 2, which were found to be uniform in visual observation, classification actually occurred, so the visual observation results in Table 3 It can be seen that the difference in color difference ΔE ^* between the granular agricultural chemical compositions indicates the difficulty in visually determining the classification.
In addition, during the classification operation of this test, the mixed granular pesticide composition of Production Example 5 + Reference Production Example 2 was sprayed up to a high position in the cylinder, whereas the granular pesticide composition of Production Example 5 was sprayed up to a high position in the cylinder. It was possible to recognize that the granular agricultural chemical composition No. 2 remained fluid at a relatively low location. In contrast to the above, with other mixed granular agricultural chemical compositions, it was not possible to recognize the difference in color tone of the individual granular agricultural chemical compositions in motion.

[Test Example 4]
33 grains of the granular pesticide composition of Production Example 5 were put into a 50 mL screw tube, then 33 grains of the granular pesticide composition of Production Example 6 were put into the same screw tube, and then 33 grains of the granular pesticide composition of Reference Production Example 1 were put into the same screw tube. The mixture is placed in a screw tube, and the screw tube is inverted once at a speed of 30 rpm to prepare a mixed granular agricultural chemical composition. Since this operation does not mix sufficiently, it is strongly assumed that the mixture is in a non-uniform state. When the mixed granular agricultural chemical composition is observed, the color tones of the grains present in the upper layer, middle layer, and lower layer are different, and it can be instantly visually determined that each granular agricultural chemical composition is unevenly present.
Thereafter, the mixed granular agricultural chemical composition is further inverted 29 times. When observing this mixed granular agricultural chemical composition, three types of granular agricultural chemical compositions with different colors are randomly mixed with each other, giving a macroscopically uniform mosaic-like appearance, and each grain is uniformly mixed. This can be visually determined instantly.
Table 4 shows the color difference ΔE ^* of any two types of granular agricultural chemical compositions among the three types of granular agricultural chemical compositions constituting the mixed granular agricultural chemical composition.

The mixed granular agricultural chemical composition of the present invention can be used for the production of highly uniform agricultural chemicals.
